How to Get Pregnant - Home Pregnancy Tests
Home pregnancy tests look for the presence, in your urine, of a natural hormone called human chorionic gonadotropin (hCG). This hormone is produced by cells in the placenta and first enters your bloodstream when the fertilized egg implants in the uterus. This happens on average about eight to ten days after fertilization. After the egg implants in your uterus, the amount of hCG in your body then starts to increase rapidly for the next few weeks, doubling in quantity every two days.
Bood Tests vs. Urine Tests
Because blood tests are quantitative (they measure the exact amount of hCG in your bloodstream), they can also be used to detect how far along you are in your pregnancy.
Home pregnancy tests are usually about 97% accurate, but this varies from brand to brand. Some urine tests can be used on the first day that your period is due, however, it is unlikely that you will achieve that 97% accuracy rate if you test so early.
They don't. They really only claim to be "greater than 99 percent accurate" in general, and then separately, they suggest that you can use them as early as the day you miss your period. According to the current Food and Drug Administration (FDA) regulations, in order to claim that a home pregnancy test is "greater than 99 percent accurate," the manufacturer only needs to demonstrate that the test performs as well in the lab as an existing test more than 99 percent of the time.
